There seem to be some open source driver out there but its GPL.... GPU acceleration for 2D and 3D is a must for us and if it is only a matter of a few programmers time and effort we can invest in it. Can there be any blocking things like proprietary software/hardware etc? -- Johannes Lundberg BRILLIANTSERVICE CO., LTD.
